IBatis一对多查询

namespace IBatis
{
public class User
{
public int UserId { get; set; }
public string UserName { get; set; }

}

public class UserRight
{
public int UserRightId { get; set; }
public int UserId { get; set; }
public int RightId { get; set; }
public string RightName { get; set; }
}

public class UserRightJoin
{
public int UserId { get; set; }
public string UserName { get; set; }

public IList UserRights { get; set; }
}
}

在Mapper的UserRight.xml中

select A.*,b.*
from [dbo].[User] a join [userright] b on a.userid=b.userid

在 sqlmap.config

然后是 DAO

public class BaseDao
{
public static ISqlMapper _sqlMap = null;
static BaseDao()
{
_sqlMap = Mapper.Instance();
}
}

public class UserDao : BaseDao
{
public IList GetList()
{
ISqlMapper mapper = _sqlMap;
IList ListPerson = mapper.QueryForList("selectAllUserRight", null); //这个"selectAllUserRight"就是xml映射文件的Id
return ListPerson;
}

}

最后是调用

static void Main(string[] args)
{
UserDao ud=new UserDao();
var lst= ud.GetList();
}
